The P values of the influence of the respective GV measures themselves, as well as effect modification and the Δ of confounding, calculated from the respective slopes (B and B′) from the regression equations, on the HbA1c-MPG relationship for all patients pooled and for type 1 and type 2 diabetic patients separately
